HYDRAULIC HOSES
The condition of all hoses should be carefully checked during a routine service of the machine. Hoses that have
been chaed or damaged on their outer casing should be securely wrapped with waterproof adhesive tape to
stop the metal braid from rusting. Hoses that have suered damage to the metal braid should be changed at
the earliest opportunity.
HOSE REPLACEMENT
Replace one hose at a time to avoid the risk of wrong connections.
When the hose is screwed to an additional fitting or union, use a second spanner on the union to avoid
breaking both seals.
Do not use jointing compound on the threads.
Avoid twisting the hose. Adjust the hose line to ensure freedom from rubbing or trapping before tightening
hose end connections.
Before changing hoses, study the installation, these are carefully calculated to prevent hose damage
during operation. Always replace hoses in exactly the same manner. This especially important for the flail
hoses where they must be crossed, upper to lower, at the dipper and head pivots.
SAFETY NOTE:
Soft Seal hose connections are capable of holding pressure when the nut is only ‘finger tight’.
It is therefore recommended that when dismantling, the hose be manually flexed, to relieve any
residual pressure, with the retaining nut slacked prior to complete disassembly.
